I think that the celebrity couple most likely to last the longest would be Aston Kutcher and Demi Moore, only because I think she is a really strong woman and knows how to get what she wants. She seems to be controlling him and turning him into her handbag puppet so I think he will be too blind and weak to leave her... Whats your opinion?

Yes I think you're right too. She is a strong woman and was quoted in a magazine for enjoying intimacy a lot, so I think the younger virilty is another factor as well. He also seems to dote on her daughters too..........
